ZOTAC also displayed an upcoming socket LGA1155 motherboard based on Intel Z77 chipset, in the mini-ITX form-factor, which is geared for overclocking, that's right, overclocking. ZOTAC has, in the past, designed a similar motherboard based on the Z68 chipset. This mini-ITX board draws power from 24-pin ATX and 8-pin EPS connectors, it supports upcoming "Ivy Bridge" Unlocked LGA1155 Core processors out of the box.

The LGA1155 socket (LOTES Black, powder-coated to prevent shrinking when subjected to subzero cooling), is powered by an 8-phase VRM circuitry, complete with a feature-rich controller, Pulse-made inductors, and driverMOSFETs (DrMOS), and High-C capacitors. The DrMOS chips are cooled by a high-density heatsink that shares some of its heat with the heatsink over the Z77 PCH, over a heat pipe.

The CPU is wired to two DDR3 DIMM slots supporting dual-channel DDR3 memory. The lone expansion slot is a PCI-Express 3.0 x16. Storage connectivity includes two SATA 6 Gb/s, two SATA 3 Gb/s, and an mSATA slot (likely 3 Gb/s). Display connectivity only includes DVI and HDMI. General connectivity includes 8-channel HD audio, gigabit Ethernet, wireless b/g/n, and USB 3.0. This board will have a feature-rich UEFI BIOS.

You're not going to get very far with 114mm of CPU heatsink headroom, and mITX cases only get smaller.

Umm its all good for my lanbox (SG-07). I put a push-pull Antec kuhler 620 with no problems in that case and have a 2500k OCed to 4.2ghz with max temps at about 55C. I also have a GTX 570 in there, although that does get a little warm at around 78-82C.

I have an H50 in there now, and its pretty good, would be able to sustain a 4.0 Ghz i750 at about 80C linpack if not for the board.

Ivy 4.5Ghz should not be out of the question.

nice setup man! Very similar to my lanbox although its in a SG-07 and i have a i5-2500k Also you might want to try having the radiator intake cool air into the case and using a more positive pressure airflow, I found it to be more effective.
